这句句子该怎么断句?(就是这句句子结构是什么,去掉修饰的东西)
When enrichment an equilibrium state has to be reached to obtain stable spectrum for the further adsorption isotherm and PLS model calculations.
When enrichment（ an equilibrium state has to be ）reached to obtain stable spectrum for the further adsorption isotherm and PLS model calculations.括号中的修饰enrichment?
enrichment富集
equilibrium state平衡态
spectrum光谱
adsorption isotherm吸附等温曲线

Answer 1

这句英语根本就不通.是什么人写的?作者应该去上英语课.
改正过的句子：
During enrichment,an equilibrium state must be reached to allow a stable spectrum to be obtained for further adsorption isotherm and PLS model calculations.
明白原句里有多少错误么?
1.When是副词,被当成介词用了.正确的介词是during.
2.have to表示不得不的意思,must是必须的意思.这句里必须用must.
3.to obtain的逻辑主语显然是实验员,可是句子里根本没有!句子里唯一的主语是an equilibrium state,它是无法去获得什么光谱的.所以正确的说法是to allow a spectrum to be obtained.
4.further前面不应该加定冠词.
改掉了所有错误之后,句子的主要结构就很清楚了：
an equilibrium state（主语） must（情态动词） be reached（谓语,被动语态）
